T 0 all whom it may concern:

Be it known that l, OLnY J. LEAR, a citizen of the United States, residing at Newport, in the county of Sullivan and State of New Hampshire, have invented a new and useful improvement in lhachines for Cementing Shoediinings, of which the following is a specification.

My invention relates to improvements in cementing side linings in shoe uppers with hot cement, at present a pot heated by steam is used for heating cement and is applied by hand with paint brush. While a machine constructed as herein shown and described would be a cement and labor savin device.

The invention consists in the novel leatures of construction, combination and arrangement of parts, hereinafter fully described and pointed out in the claims.

in the drawing forming a part of this specificationz-Qhigure 1 is a plan view of the device. 2 is a side view, looking toward the end of a rotatable drum. Fig. 3 is section on the line 33 of Fig. 2. Fig. 4 is a section on the line 44 of Fig. 2. Fig. 5 is a sectional view taken at right angles to Fig. 3.

in constructing the machine I employ a base socket 1, in which is adjustably mounted a supporting standard 2, upon which is a hollow metal base 3, on which is mounted a shallow tray 4, and a tank 5 which is provided with an opening 6 affording communi cation with the tray and closed by a vertically movable gate 7 provided with an upright 8 which is engaged and operated by a pivoted lever 9. Upon the base 8 and on opposite sides of the tank are placed suitable bearings 10 through which run a steam pipe 11, the ends of which open into the hollow base 3 and on opposite sides of the same.

A hollow axle 12 is mounted on the steam pipe 11 between the bearings 10 and on said axle is secured a steam-tight drum 13, the pipe and axle being perforated as shown at 14, so that steam is admitted. within the drum. Outside of the drum a gear-wheel 15 is lined on the axle 14 and is inclosed by a suitable casing 16 which also incloses an illterineshing gear 17 mounted upon a powershaft 18, upon which shaft is also mounted a l l l fixed pulley 19 and an idle pulley 2O driven by a belt 21. An adjustable slide 22 is mounted on the tray 4 immediately in advance of the drum and. by moving the same toward or away from the drum the amount of cement carried upwardly by the drum from the tray 4 can be regulated. The front of the tank 5 carries a scraper 23, which rests upon the upper portion of the drum and scrapes therefrom the unused cement returning the same to the tank 5.

The cement is kept in the tank 5 and admitted as required into the tray 4 by lifting the gate 7. Steam is admitted through pipe 24 into the base 3 and heats the bottoms of the tray and tank and also passes through the pipes 11 into the drum which is heated sufficiently to prevent the cement thickening upon the drum surface. Two operators can work on each machine sitting upon sides of the sa re, a suitable table being provided to hold the work. The operator takes the work to be cemented between the thumb and "lingers of both hands pressing the work against the drum and then places the work or parts upon which cement has been applied against the part to be cemented to it, smoothing down with the hand. C ement not taken from the drum by this operation will be removed by the scraper and will be fed back to the tank where it will become reheated, and. can be again admitted to the tray.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 2 1. A device of the kind described comprising a hollow base, a steam pipe discharging into said base, tray mounted. on the base, means for feeding heated cement to the tray, a continuous steam pipe leading from the ends of the base and having a perforated portion above the tray, and a hollow druin mounted rotatably on said pipe and inclosing the perforated portion of the pipe.

2. A device of the kind described, a hollow base, a tray mounted upon said base, a tank mounted on the base and communicating with the tray, a gate regulating communication between the tank and tray, a rotatable drum receiving cement from the tray, and the tank to the tray, and an adjustable slide means for admitting steam into the hollow I carried by the tray and movable and toward 10 base and from the base into the drum. 1 and away from the drum.

3. A device of the kind described compris- 5 ing a steam-heated base, a steam-heated OLEY JOSIAH LEAR drum, a tank arranged in the rear of the I WVitnesses:
